Subject: [PATCH 2/2] x86: use sparse_memory_present_with_active_regions() on UMA
Date: Thu, 07 May 2009 15:35:42 +0300 [thread overview]
Message-ID: <1241699742.17846.31.camel@penberg-laptop> (raw)
From: Pekka Enberg <penberg@cs.helsinki.fi>
There's no need to use call memory_present() manually on UMA because
initmem_init() sets up early_node_map by calling
e820_register_active_regions().
[ Impact: cleanup ]
